Because there's a lot of people that just like mainstream, autotuned sh*t that's barely even music. The reason for that is because when you're in school or what have you, people will ALWAYS be obessed with whatever is in style, and in order to fit in, people will start liking it no matter what. At one point of my life I got sick and tired of people ignoring me all the time so I started listening to Justin Bieber... I didn't even like him I just did it for the sake of my social life. It didn't last long, after a few months I just said screw it. If people would just be themselves and not pretend to like all this crap, maybe artists would be more inspired to write better music.
